Hi, I understand that although normals are directed perp to the flat polygon surface, they are define at the points. So when defining something such as a triangle strip, or fan, or quad strip, or anything where different flat surfaces are sharing vertices, how do you properly define the normals? For example:
So you could get two connect traingles that are not on the same plane. But for the second triangle the normal is only correctly defined for one vertex. Is there some way to assign more than one normal to a vertex? Or what do I do here? Can I not use GL_TRINAGLE_STRIP?
